Title: Improvements in or relating to dishwashing machines
IPC: A47L15/06
Filed: 1953-10-12
Abstract: 733,598. Centrifugal pumps. JAMES, L. A., and JAMES, D. A. Oct. 12,1953, No. 28003/53. Class 110 (1). [Also in Group XXIII] Relates to a centrifugal pump assembly in a distributing machine (see Group XXIII). The impeller housing 16, Fig. 2, comprises a substantially cylindrical shell 28, the ends of which fit over flanges 26, 27 of end walls 19, 20 respectively. The  impeller blade 34 in the form of a single sheet of metal is provided with a plurality of longitudinally spaced cuts extending across the axis of the blade and the alternate portions of the blade defined by the cuts are pressed-out laterally in opposite directions to form a bore to receive the impeller shaft 25 journalled in bosses 21, 22 of the end walls 19, 20. The blade 34 is given a longitudinal twist of 180 degrees. A baffle 18 in the form of a sheet of metal twisted longitudinally through 180 degrees in the opposite sense to the impeller blade, is provided with end trunnions 46, 47 journalled in bosses 42, 43, in extensions 40, 41 of the end walls 19, 20. A driving connection between the impeller shaft 25 and the trunnion 46 is housed between the end wall 19 and a cover-plate 50. The impeller housing is secured between end. walls 4 of the dish-washing machine tube 2, with the interposition of gaskets 13, 14 by. screws 64 passing through the wall 19, coverplate 50 and one tube wall 4. A prime mover (not shown) is connected to the shaft 25 which extends through seals to the outside of the tub 2. Referring to Fig. 4, an eccentric 55 fixed on the shaft 25 is rotatable in a two-part strap 56 having a detent 57 extending therefrom, the two parts 58, 59 of the strap being held round the eccentric by a spring 60. As the eccentric rotates the detent 57 intermittently imparts rotation to a ratchet-wheel 62 fixed on the trunnion 46, and thus rotates the baffle in the same direction as the impeller blade. Rotation of the ratchet-wheel in the opposite direction is prevented by a spring pawl 63. When the impeller assembly is fitted in the tub 2, Fig. 3, the inlet 30, in the form of a slot extending over the length of the shell 28, and covered by a filter screen 31, is positioned below the level of washing liquid 6 in the tub 2. As the impeller rotates liquid is drawn into the shell 28 and delivered through the outlet 17 in the form of a slot extending over the length of the shell, in a vertical direction. This liquid engages the baffle 18, the rotation of which causes it to sweep transversely of the tub over articles 11 supported in a rack 12. Some liquid is directed past the outlet and returned within the shell 28 against the filter 31, to free it of any clogging material. With this construction, of impeller blade and baffle liquid is delivered in a jet moving longitudinally and transversely of the tub 2. The outlet 17 of the shell 28, Fig. 3, is closable by a valve in the form of a plate 67 hinged at 68 and controlled by a float 75 through a linkage.

Title: Improvements in and relating to containers or magazines and lighters for cigars or cigarettes
IPC: A24F15/10
Filed: 1930-09-20
Abstract: 363,646. Cases for dispensing cigarettes &c. COCKETT, J. A., 74, Chestnut Avenue, Walthamstow, London. Sept. 20, 1930, No. 28187. [Class 18.] In an apparatus in which a cigarette &c. is fed from a magazine on to a holder and lighted by suction and frictional ignition means, the parts are controlled by means of a member 9 pivoted to an arm 7 on the piston-rod 5 of a pump 4. On pulling out the rod 5 to a limited extent, the end 92 of a lever 88 moves down a cam 94 on the member 9, thereby operating a link 86 and levers 82, 75 to raise a slide 73 and permit a cigarette to roll down the inclined bottom 72 of the magazine on to a holder 22. The slide 73 operates levers 101 thereby enabling a second slide 105 to be moved downwardly by a spring 107 to prevent the next cigarette rolling down to the holder. The slide 105 operates a pivoted flap 109 for jogging the cigarettes in the magazine. A socket 14, connected by a tube 16 to the pump 4 and provided with one or more rubber washers for gripping the end of the cigarette, is moved against the latter by a spring 18 when a cam 10 on the member 9 moves clear of a member 12 on a slide 13 carrying the socket and presses the other end of the cigarette against a stop 112. At the same time, a projection 69 on the member 9 is withdrawn from engagement with a projection 64 on the hooked end of a spindle 51 and a lever 40 is moved by a spring 42 to rotate the spindle to lift a cover 55 thereon from a wick holder 56 and operate a friction-wheel 27 for igniting the wick. The lever 40 is connected by links 38, 48 to an arm 50 on the spindle, the link 38 being connected to a lever 34 having a recessed head engaging pins on the wheel 27 under the action of a spring 35. The piston-rod 5 is then reciprocated so as not to move the member 12 and thereby draw air through the cigarette to facilitate ignition and is finally moved outwardly to the full extent and the ignited cigarette removed. During the final outward movement of the rod 5, the socket 14 is retracted by a cam 11, the lever 40 is operated by a projection 47 on the member 9 engaging a lever 45 to rotate the spindle 51 and close the cover 55, and a projection 68 on the member 9 moves a trigger 66 over the projection 64 to retain the spindle with the cover 55 in the closed position. When the rod 5 is pushed in to the full extent, the projection 69 moves the trigger 66 out of engagement with, and itself re-engages, the projection 64, all the parts being then in the normal position.

Title: Yarn packages and winding methods therefor
IPC: D01H1/30
Filed: 1972-06-16
Abstract: 1429647 Polyamide yarn package LMPERIAL CHEMICAL INDUSTRIES Ltd 14 June 1973 [16 June 1972] 28298/72 Heading B8M [Also in Divisions D1-D2] In a package of draw bulked, i.e. drawn and bulked without intermediate wind-up, synthetic polyamide yarn, the yarn possesses substantially constant retraction, i.e. shrinkage that occurs in yarn under compressive forces that exist within wound yarn packages, throughout its wound length. The substantially constant retraction is achieved by winding the yarn throughout the winding period under conditions of gradually changing wind-on tension according to a programme including at least two tension maxima, in which the tension is increased from the start of the period to a first maximum, decreased to a minimum, increased again to a second maximum lower than the first and then decreased again. The change in balloon tension according to the desired programme, and the change in spindle speed necessary to achieve the required balloon tension, are preferably brought about by suitably profiled cams. The winding is preferably done on a ring and traveller assembly.

Title: Method of producing floats for buoying fishing nets
IPC: B21D51/00
Filed: 1960-08-16
Abstract: 881,447. Fishing-floats. SCHMIDT G.m.b.H., KARL. Aug. 16, 1960 [Aug. 24, 1959], No. 28428/60. Class 48. [Also in Groups XXII and XXVIII] A float for a fishing- net is made by assembling two pressure diecast hemispherical shells in an airtight manner and reducing the pressure inside the float so that the pressure of air or water on the outside of the float holds the shells together. The abutting edges of the shells may have tongues and grooves and rubber or plastic rings may be inserted in the grooves. The reduced pressure inside the float may be produced by assembling the hemispheres when hot, the subsequent cooling reducing the pressure; alternatively air is withdrawn through a tapered hole in one of the hemispheres by a pump and the hole is then plugged. The latter method is facilitated by the apparatus shown which comprises a head 3 connected to a pump by a pipe 6 and having an opening 4 which is placed over the hole 2 in the hemisphere. When the desired vacuum has been attained a plug 8 from a magazine 7 in the head 3 is tapped by an electromagnet 9 into the hole 2.

Title: Differential refractometry
IPC: G01N21/41
Filed: 1965-07-08
Abstract: 1,097,526. Refractometers. E. ST. CLAIR WATSON. July 8, 1965 [July 13, 1964], No. 28998/65. Heading G2J. [Also in Division G1] The difference in refractive index between a reference and a sample material is measured using a test cell in which these materials each form an interface with a common surface of a single third material, light being passed through the latter and being detected after leaving the interfaces. The test cell for liquid samples comprises a casing (10, Fig. 1, not shown) containing two right-angle glass prisms (12, 14) forming between them a space in which is located a thin plastics gasket having two cut outs to define volumes for reference and sample liquids, such that single samples may be examined. If a sample or reference stream is required for continuous measurement, the gasket is suitably chambered with inlet and outlet channels. Light entering the prism (12) at an angle to the interface near to the critical angle for the glassliquid interface, is partially reflected and partially transmitted, according to Fresnel's laws. The variation in the transmitted light intensity, as a result of a change in the refractive index of the liquid, is more pronounced than that of the reflected component for the same change, and the embodiment described therefore employs the transmission mode of operation. In cases where the absorption of the sample is high, the reflection mode is preferable. The optical system comprises a light source 58, which may emit visible, u.v. or i.r. radiation, imaged on a slit 62 by lens 60, followed by collimator 64, test cell 66 and a lens 72 which focuses light from the cell on to an apertured mask 74 (also Fig. 9, not shown) having two openings, one corresponding to the sample and the other to the reference chamber. A chopper disc 76 driven by motor M allows light to reach the openings alternately such that the light reaching the detector 82, a photo-resistor (e.g. cadmium selenide cell) is of square waveform. The detector output is amplified (at 106) and demodulated by photosensitive resistor 94. This receives light every alternate half cycle from a source 90 located at the other side of the chopper 76 and acts as an on-off switch passing only the positive half cycles of the amplifier output. The signal passed to the recorder 108 represents the difference in the sample and reference beam intensities. In other arrangements, the chopper may be positioned before the test cell or no chopper is used at all, two detectors being used, one receiving light from the sample and one from the reference chamber. An application of the invention is its use in liquid chromatography. An example described relates to samples of sucrose solution using water as a reference. The instrument is calibrated in this case using samples of known refractive index.
